Precautions for the selection of high-gloss non-marking plastic materials The selection of a high-gloss plastic material currently uses high-gloss plastic materials such as PC, ABS+PC, PC+PMMA, ABS+PMMA, PC+GF and so on. As a common case material, although the cost of ABS+PC is larger, the molded product is better than others in impact resistance, surface gloss and hardness, so it is usually used in the production of high-gloss products. It is a high-gloss ABS material. ABS is an amorphous polymer with no apparent melting point. Due to the wide variety of grades, appropriate process parameters should be formulated according to the grades in the plastic injection process, generally above 160 ° C, below 270 ° C. In the molding process, ABS has good thermal stability, and the range of choice is large, and it is not easy to degrade or decompose. And ABS has a moderate melt viscosity, and its fluidity is better than that of polybenzene (PC), polycarbonate, etc., and the melt solidification speed is faster than that of ruthenium, and generally it can be cooled in 5-15 seconds. The fluidity of ABS is related to both the injection temperature and the injection pressure, with the injection pressure being slightly more sensitive. For this reason, it is possible to start from the injection pressure during the molding process to lower the melt viscosity and improve the filling performance. ABS has different properties of water absorption and water adhesion due to different components. The surface adhesion water and water absorption rate are between 0.2% and 0.5%, and sometimes between 0.3% and 0.8%. In order to obtain a more ideal product, Drying is carried out before molding to reduce the water content to less than 0.1%. Otherwise, bubbles on the surface of the part, such as bubbles and silver threads, will appear. Can always use 1% metal powder for plastic materials Garlic.Ginger.onion.peeled Onion.peeled Garlic.frozen Onion Pieces garlic.Ginger.onion.peeled onion.peeled garlic.frozen onion pieces henan junzhian food co., ltd , https://www.junzhianfood-onion.com
